Patented May 18, 1948 UNITED STATES PATENT OFFICE LOADING DIVIOI FOB TRUCKS OR OTHER mom VEHICLES James Edward Owen, amine, u. 0. Application Jane 18, 1248,8orlal No. 617,543 4 cum. (cl. 214-18) 1 This invention relates to a loading device which is particularly designed to provide a device which installed on a truck or other vehicle will permit the operator thereof to load his truck without the use of additional equipment.

The use of such a loader cuts loading and digging costs since it eliminates the need of extra It will save time since trucks so equipped willlnot have to stand in line'to be an the invention is to provide a loader that is durable in use operated by hydraulic action having a minimum-f moving parts which will perform its tasks in an expeditious and efiicient manner and can be installed on any type or other vehicle in use at the present time.

With the above and other objects and advantages in view the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accom- P51171118 drawings in which: Figure 1 is an elevational view of an embodiment of the invention installed on a dump truck;

Figures 13 to 1'1 inclusive are diagrammatical views of the loader in operation: and

Figure 18 is a diagrammatical view of the hydraulic control system.

Referring more reference numeral 22 designates a dump or similar truckto which the loader embodying the invention is attached.

The means for mounting the loader on the truck comprises a rear saddle 22 as best shown in Figure 4 which comprises the top bar 24 having in detail .to the drawing the 'nov 8 1949 the straight portion 2! and inclined portions 2| which are bent downward at II to form the aligned vertical portions 22.. a

'The straight portion-2i is secured at 84 to the upper longitudinal edge of the truck frame channel members it and angular members a are secured by welding or the like at 4| to the straight portion 20, at 42 to the vertical sides of the memhere 20, and at 44 to the lower end of the portions 32 Y r secured to the members 32 at their point of angularity 40 by fasteners 48 is the tubular tie rod II and the saddle 22 is positioned or mounted on the truck directly below the rearmost transverse edge of the cab II of the truck 2|.

Mounted forwardly of the saddle 22 at the rear edge of the front fenders I of the truck 2. is the under frame I! which is best seen in Figure 5 and this frame comprises the horizontally deposed beam ll having the vertical members I. secured at O2 to the beam If and at It to the truck frame 2|. vA plate 60 underlies the frame 22 and secured thereto at O2 to the member II and at II to the frame fl and a short vertical member spaced from in parallel relation with the members ,0! is secured by welding or the like at 12 to the beam I2 and at 14 by welding or the like to the plate I.

' welding to the members 22.

Secured to the outer opposite ends of the beam 82 and'to' the portions 22 at It and I8 respectively are the inverted T-bars ll which form the side frames and supports for the loader. Secured by welding to the bars 2| album the ends of the beam it are the arcuate arms 22 which are secured by welding or the like at N to the vertical bar II which is secured at 82 to the bars 20. Secured in contact with the bars II by the same securing means for the bars are the arms II and spacers 82 are positioned intermediate the arms 90 and the bars 20 to compensate for the base of the bars and to-align the arms ll. At the forward end of the arms a shaft 94 journaled in the arms otally mount the A frame 9' thereon and a triangular brace 22 secured to the forward end of the bars I. act as stops for the arms II. for

the A frame It aswell as stops Ill secured by Pivoted on the arms II at I02 are the hydraulic cylinders I having the pistons .lli therein which are connected at III to the'plate lll welded to the arms I" adjacent the pivot ll and the cylinders Ill cause the actuation of the arms through the proper manipulation of controls and in the bars 2. pivmounted in the cab II at a convenient location to the driver thereof.

Secured to the arms Ill adjacent the'plate, III are the brackets 2 to which are connected at III the hydraulic rams I I. which are connectedat III to the triangular plates I20 secured to the arms I22 which are pivoted at I24 to the arms I and a bearing plate I2 is mounted on the pivot I24 intermediate of the arms '-IIIl-and I22. A semicircular flange I22 connected to the arm -l III is spaced from and follows the contour of the plate I26. A bearing III! is secured by weldingin the arm I" and retained therein by circular rings or braces I22 secured interiorly of the arms I" and sectional nuts I are secured on the pivot I24 by bolts iii. The pivot ll is provided with a lubrication fitting I22 in the arms I" and a bucket I" is secured to the free ends of the arms I22 by fasteners I42 and tubular spacing members I are secured to the free ends of the go arms I".

Secured to the rear of the cab 50 on the dump body of the truck are T-shaped supports I on which the arms I22 rest when the loader is in position for movement of the truck.

The loader operates by hydraulic pressure using oil and the arrangement forthe operation of the loader is shown in Figure 18 wherein there is shown the reservoir tank I48 connected to the pump I50 which in turn is connected to control valves I52 and I, valve I52 being for the operation of rams I I6 and valve In for the operation of cylinders I04.

Thus when in operation the loader is driven into a pile of dirt or other material to be moved so and the bucket is pushed into the dirt to be filled and then elevated to dump the contents thereof into the truck.

Thus the driver can load his truck and after the loading thereof position the loader in carrying position and move the truck to further dump the contents thereof at any desired location.

It is believed that the operation and construction of the invention will be apparent to those skilled in the art and it is to be understood that 5 changes in the details of construction, operation and arrangement of parts may be resorted to provided they fall within the spirit of the invention and the scope-of the appended claims.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

l. A device of the character described, in com- 4 bination with a truck having a body and a frame, comprising transverse parallel saddles secured to the frame below the body, side frames secured to said saddles at the outer ends thereof on opposite sides of said chassis in parallel relation to each other, A-frames secured to said side frames at the forward ends thereof, hydraulically actuated cylinders pivotally connected to said A- frames and said side frames for the raising and lowering of said A-frames, parallel spaced arms pivotally connected to said A-frames, a bucket secured to the free ends of said arms, a hydraulically actuated cylinder connected to said arm frame and said arms for the raising and lowering of said arms, and means for supporting said arms when said A-frame is in raised position.

2. The invention as in claim 1, wherein stops are provided on said side frames for limiting the movement of said A-frames.

3. The invention as in claim 1, wherein brackets are provided on said arms, and said A-frame for connecting the hydraulic cylinders thereto.

4. A loading attachment for trucks having a body and a frame, comprising a vertical swinging A-frame, saddles on said truck frame, side frames connected to the opposite ends of said I saddles for supporting said A-frame forwardly of the truck body, a pair of parallel opposed arms pivotally connected to the opposite sides of said A-frame, and adapted for vertical swinging movement with regard to said truck frame, on opposite sides thereof, a. bucket secured to t e forward ends of said arms, hydraulically actuated cylinders connected to said side frames and said A-frame for the raising and lowering of said A-frame, hydraulically operated cylinders connected to said arms and said A-frame for the raising and lowering of said arms, and means on said body for supporting said arms when in full raised position.
